Study on Well Deployment Optimization Technology of Tight Sandstone and Rich Water Gas Reservoir in the Sulige Gas Field of West Area

Sulige gas field is the largest natural gas field discovered on land in China so far. With the continuous development of Sulige gas field, the eastern and central regions with better resource endowment are facing great pressure of stable production, and the reserve development and production area is gradually changing from rich gas area to tight and rich water area. Sulige west area is located at the lower position of the gas field structure, high water saturation, more complex gas-water relationship and large-scale water cut in the area. Due to the above reasons, the development of Sulige west area is faced with the problems of more difficult well deployment and lower success rate of drilling and gas acquisition. Based on the understanding and effect of production, construction and development in the west area over the years, and on the basis of making full use of regional geological, seismic, logging, dynamic and other data, this study carries out high-quality reservoir recognition and hydrocarbon detection research, and explores and forms a set of well deployment optimization technology suitable for the benefit development of tight sandstone and rich water gas reservoir in Sulige west area.
